多个日志文件创建的log4j滚动追加程序问题

Question

I am using log4j for my application for printing logs. Till now, I have only one log file(say X.log) and it is getting rolled after a fixed size, say, 4 MB. Now , I am trying to log some particular requests and responses to a different log file, Y. Log.

My requirement is to roll the Y.log file also, after 4 MB. I am using rolling file appender for both X and Y logs. Y.log will be created in the same location where X.log is available.

But it seems like now both the log files are not getting rolled over after 4 MB. It is keep on appending to the same logs and the size is increasing. Below is my log4j configuration.

<appender name="Xlogfile" class="org.apache.log4j.RollingFileAppender">
    <param name="append" value="true" />
    <param name="file" value="/logs/X.log" />
    <param name="MaxBackupIndex" value="200" />
    <param name="MaxFileSize" value="4MB" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d{dd MMM yyyy HH:mm:ss} %5p %c{1} - %m%n"/>
    </layout>
</appender>

<appender name="Ylogfile" class="org.apache.log4j.RollingFileAppender">
    <param name="append" value="true" />
    <param name="file" value="/logs/Y.log" />
    <param name="MaxBackupIndex" value="200" />
    <param name="MaxFileSize" value="4MB" />
    <layout class="org.apache.log4j.PatternLayout">
          <param name="ConversionPattern" value="%d{dd MMM yyyy HH:mm:ss} %5p %c{1} - %m%n"/>
    </layout>
</appender>

<root>
    <level value="INFO"  />
    <appender-ref ref=" Xlogfile " />
    <appender-ref ref=" Ylogfile " />
</root>

Could anyone please provide me a solution for this. Thanks in advance.

Try adding a policy to your appender, like this:

<Policies>
    <SizeBasedTriggeringPolicy size="4mb"/>
</Policies>
